Patent JP-H01228314-A (JP)
Title: Filter device
Inventor: FUJII KENSAKU
IPC: H03K4/94
Filed: 1988-03-09
Abstract: PURPOSE:To extend the dynamic range, reduce the circuit scale, and increase the operation speed by selecting a prescribed rise value or fall value based on the result of comparison between signal levels of the input signal and the output signal of a filter and operating and outputting a new filter output signal based on the selected value and the filter output signal. CONSTITUTION:An input signal A and a delay output signal B obtained by delaying a filter output signal C in a delay device 4 by a time corresponding to one sampling period are inputted to a comparator 1 and are compared with each other, and a comparison output D indicating the comparison result is sent to the control input terminal of a selector 2. A selected output E of the selector 2 is inputted to an adder 3. The adder 3 outputs the output signal C which is gradually increased with a step width alpha when the selector 2 selects the rise constant alpha, and the adder 3 outputs the output signal C which is gradually reduced with a step width beta when the selector 2 selects the rise constant -beta. Thus, the dynamic range is extended though this device is used for purposes of slow rise characteristic such as noise intensity detection. Multiplying circuits in the circuit are removed to not only reduce the circuit scale but also increase the operation speed.

Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To reduce printing heat energy by applying recording heat energy to the recording layer of the liquid crystal display medium, having a liquid crystal/polymer composite film on a conductive substrate, while the recording layer is preheated. SOLUTION: While the recording layer of the liquid crystal display medium having the liquid crystal/polymer composite film formed as the recording layer on the conductive substrate by dispersing smectic liquid crystal in a polymer matrix is preheated, the recording heat energy is supplied to the recording layer. Namely, a conveyor roller 2 carries a card onto a base 1, where a hot press is lowered to preheat the card. The preheated card is sent by the conveyor roller 2 as shown by an arrow and mounted on the base 2, where desired characters and images are printed by a thermal head. The card which is thus recorded is sent out of the system by a conveyor roller 3 and cooled to store the recording information.

Title: Photovoltaic power generating equipment capable of jointly using battery
Inventor: KITAMURA AKIO
IPC: H02J7/35
Filed: 1993-03-16
Abstract: PURPOSE:To make the power generation capacity of a solar battery maximum, and to effectively utilize solar radiation energy by operating a DC/DC converter and controlling the output voltage of the solar battery so that the generated power of the solar battery becomes maximum. CONSTITUTION:At the time of supplying electric power from a solar battery 1 to an inverter 3, a DC/DC converter 5 controls an output voltage of the solar battery 1 so that the generated electric power of the solar battery 1 becomes maximum. When the generatable maximum electric power PPVL of the solar battery 1 is smaller than the consumption electric power PINV of the inverter 3, insufficient electric power obtained by subtracting the generated electric power PPVI of the solar battery from the consumption electric power PINV of the inverter 3 is supplied by electric power supply caused by discharge of a battery 4. On the other hand, when the generatable maximum electric power PPVI of the solar battery 1 is larger than the consumption electric power PINV of the inverter 3, surplus electric power obtained by subtracting the consumption electric power PINV of the inverter 3 from the generated electric power PPVI of the solar battery 1 is used for the charging of the battery 4.

Filed: 1979-05-07
Abstract: PURPOSE:To make power consumption low by constituting the oscillating circuit and the buffer circuit only by enhancement MOSs and making it possible that the output node point rise up to the power source level. CONSTITUTION:Oscillation inputs of phases opposite to each other are input to node point inputs B12 and B13 of MOSFETs A2 and A16 which drive MOSFET A9 of an inverter, thereby preventing DC currents from flowing to FETs A2 and A16. Assuming that input B12 is a high-level, input B13 becomes low-level, and input B2 is charged to a high-level by FET A2, and oscillation output B changes from the high-level to the low-level after a voltage lower than the power source by 1/T is charged in capacitor C2, and MOSFET A23 is turned off. The level of node point input B9 rises through FET A9, and input B2 is raised to a level of the power source or more by capacitor C2, and FET A9 becomes the nonsaturation state, and the level of input B9 is lowered to the power source. Next, input B12 becomes low-level, and the output of input B9 is lowered to the low-level.

Title: Starter device of miniature engine
Inventor: MORISHIGE TOSHINORI
IPC: F02N15/04
Filed: 1990-03-07
Abstract: PURPOSE:To prevent the reverse rotation of a motor by starting a clutch plate and a centrifugal ratchet as they are in normal engagement at the time of positive rotation, and releasing the engagement by a release cam rotatable only in positive rotating direction by a one-way clutch when the engine rotates reversely. CONSTITUTION:When a motor 14 is rotated, a final gear 6 is rotated to rotate a clutch plate 9, which pushes and rotates a release cam 10. At this time, the engagement part 9b of the clutch plate 9 is engaged with a centrifugal ratchet 18, and an engine starts rotating. After starting, the engagement is released. In the case of reverse rotation at the time of en-st by engine overload and stop, the ratchet 18 is pushed inward by a return spring 19 as the centrifugal force of the ratchet 18 is reduced, and the clutch plate 9 engaged with the ratchet 18 starts to resversely rotate. As a cam 10 never reversely rotate due to a one-way clutch 11, then, the ratchet 18 is pushed outward against a spring 19 on the inclined surface 10a of the cam 10, and the engagement with the clutch plate 9 is released, so that the gear 6 is never reversely rotated even if the engine continues reverse rotation.

Abstract: PROBLEM TO BE SOLVED: To prevent temperature fluctuations associated with the introduction of a sample in a thermostatic tank by providing a partition wall to buffer heat transfer between a valve for injecting a sample and a column in the thermostatic tank. SOLUTION: A carrier liquid is sucked from a reservoir 1 to a liquid delivering pump 2, pressurized, delivered through a valve 3 for sample injection and a column 4, passed through a detector 5, and is made to flow out. A sample is injected to the valve 3 for sample injection by a syringe 11, introduced into the channel of the carrier liquid, and separated into each component in the process of passing through the column 4, and its concentration is converted into an electric signal at the detector 5. A partition wall 10 to buffer heat transfer is provided between the valve 3 for sample injection and the column 4 in a thermostatic tank 7. By this, disturbances in temperature caused by the introduction of the sample at room temperature are prevented from reaching the overall thermostatic tank 7.  Consequently, as the temperature of the column 4 is stabilized, the reproducibility of measurement results is improved and the stability of a base line is improved especially in the case of using the detector 5 sensitive to temperature changes.
